"Clicking" option element via WebDriver the second time doesn't fire change event, even though the selection has been changed via JavaScript. Steps to Reproduce (see the attached script): 1. Create a <select> with two <option> 2. Listen to the change event of the <select> 3. Select ("click") the second <option> via WebDriver 4. Select the first <option> via JavaScript 5. Select ("click") the second <option> via WebDriver Expected Results: A change event is fired at step 5 Actual Results: No change event is fired at step 5 My environment: * Arch Linux * webkit2gtk 2.32.4-1 * python 3.9.7-1 * python-selenium 3.141.0-3 My educated guess is that WebKit::WebAutomationSessionProxy::selectOptionElement should call WebCore::HTMLSelectElement::saveLastSelection before calling WebCore::HTMLSelectElement::optionSelectedByUser. 1810435 1 webkit-bug-importer 2021-10-30 11:35:15 -0700 <rdar://problem/84841212> 442270 2021-10-23 11:34:15 -0700 2021-10-23 11:34:15 -0700 Python script to reproduce the problem. file_232202.txt text/plain 1038 johnchen902 aW1wb3J0IHNlbGVuaXVtLndlYmRyaXZlcg0KaW1wb3J0IHRlbXBmaWxlDQoNCmRlZiBydW5fd2Vi ZHJpdmVyKHVybCk6DQogICAgd2l0aCBzZWxlbml1bS53ZWJkcml2ZXIuV2ViS2l0R1RLKCkgYXMg ZHJpdmVyOg0KICAgICMgd2l0aCBzZWxlbml1bS53ZWJkcml2ZXIuRmlyZWZveCgpIGFzIGRyaXZl cjoNCiAgICAgICAgZHJpdmVyLmdldCh1cmwpDQogICAgICAgIGRyaXZlci5leGVjdXRlX3Njcmlw dCgnJycNCiAgICAgICAgICAgIHdpbmRvdy5DT1VOVCA9IDA7DQogICAgICAgICAgICBmb28uYWRk RXZlbnRMaXN0ZW5lcignY2hhbmdlJywgKGUpID0+IHdpbmRvdy5DT1VOVCsrKTsNCiAgICAgICAg JycnKQ0KICAgICAgICBiYXIgPSBkcml2ZXIuZmluZF9lbGVtZW50X2J5X2lkKCdiYXInKQ0KICAg ICAgICBiYXIuY2xpY2soKQ0KICAgICAgICBkcml2ZXIuZXhlY3V0ZV9zY3JpcHQoImZvby52YWx1 ZSA9ICcwJyIpDQogICAgICAgICMgZHJpdmVyLmV4ZWN1dGVfc2NyaXB0KCJmb28uZm9jdXMoKSIp DQogICAgICAgIGJhci5jbGljaygpDQogICAgICAgIHByaW50KCdFeHBlY3RlZCAyLCBmb3VuZCcs IGRyaXZlci5leGVjdXRlX3NjcmlwdCgncmV0dXJuIENPVU5UJykpDQoNCmRlZiBtYWluKCk6DQog ICAgd2l0aCB0ZW1wZmlsZS5OYW1lZFRlbXBvcmFyeUZpbGUoc3VmZml4PScuaHRtbCcpIGFzIGY6 DQogICAgICAgIGYud3JpdGUoYicnJw0KICAgICAgICAgICAgPCFET0NUWVBFIGh0bWw+DQogICAg ICAgICAgICA8dGl0bGU+eDwvdGl0bGU+DQogICAgICAgICAgICA8c2VsZWN0IGlkPSJmb28iPg0K ICAgICAgICAgICAgICAgIDxvcHRpb24gdmFsdWU9IjAiPjA8L29wdGlvbj4NCiAgICAgICAgICAg ICAgICA8b3B0aW9uIGlkPSJiYXIiIHZhbHVlPSIxIj4xPC9vcHRpb24+DQogICAgICAgICAgICA8 L3NlbGVjdD4NCiAgICAgICAgJycnKQ0KICAgICAgICBmLmZsdXNoKCkNCiAgICAgICAgcnVuX3dl YmRyaXZlcignZmlsZTovLycgKyBmLm5hbWUpDQoNCmlmIF9fbmFtZV9fID09ICdfX21haW5fXyc6 DQogICAgbWFpbigp
